L i a, citizen of the imited Shares of ihxnerica, re-

siding at 'Washington. in the District of Columbia, have HlVGi'lllQCl certain new and useful llmprovemenlts 11o lllolds for Concrete form when set either solid or hollow walls."

Cone of the primary objects of this inven lion is to, provide a mold and attachments therefor which may be used as a hail. in the construction of hollmv walls and the make up of the sides are such that a plurality of the side pieces may be assembled for use in the erection of ei'rher solid or hollow walls, which will he ii'iolded in lengths rather than in short sect ons blocks.

The means used in the construction of walls from plastic. material comprises side plates or units which may he used in pairs with suitable ties and inner plates to form a block-mold such s l plates being adapted to he associaled w form the sides of a trough into which the cement isplaced until set. the s" is plates and ties or connecting: memos lacing or such construction that they may he associated with parts to form the character of wall desired and with means for manipulating the mold so that me sides may be readily ren'ioved from the l wail after the plascic material has set or hardened. as in practice the troughs are (.HllilQClKKl or as iciated with a similar set of side pieces which contain cement which forms a lower crmrse and carries the ripper set of molds. The lmitsorsides pieces either indiridoall or when associated are connected by cross bars. which are subseqnentlv removed from the wall. and permanent ties are used to connect the. sides of the wall. The sides pieces which form a trough or mold are adapted to maintain facing and scoring or lurrowiire means as well as in denting strips or hare whirli are adapted to' form recesses in theouler face of the wall. as will hereinafter more lolly appear.

illustrate a preferred form of mold and the parts which are adapred to he used in corn. nection therewith for the purpose of constructing or molding of walls for buildings, Figure l is a perspective view lustrating the construction. of'the side-plates and show ing the side-plates in position for use in the Fig. 2, is plan view of one of the side-plates, before being'bent to provide flanges, the parts being," subsequently bent at right angles on file. dotted lines. Fig. 3 is a side elevation showing in detail the corner portions of adjacent of tie bars hollow walls and means for associating connecting means for the sideplates thereto. Fig. 6 1s a detail perspecnve view of a connecting bar for the side-plates of'the mold. Fig. 7 is a detail-perspec view of a modified form of connecting bar. Fig. 8 is an end elevation of the tie-bars, shown in Figs. 4 and 5. Fig. 9 is a sectional view of a mold for a single block. Fig. 10 is a detail view of a scoring attachment. Figs. 11 and 12 are detail views of attachments for grooving or recessihg the face of the cement. Fig. 13 is a side elevation showing means'for manipulating the molds when the side-plates are connected in series. Fig. 1- is a plan View of the mold and attacl1- ments shown by Fig. 9. are detail views of braces for the inner plates of the mold.

The side-plates 1 of the molds shown by the accompanvine' drawings are each made from a flat rectangular sheet of metal and as fully shown by Fig. 2 0f the drawings the corners are cut away to provide recesses 2 that are not quite as wide as intermediate recesses 3, which are formed in the sides of the blank. The plate or blank is also shaped to provide when bent flanges l, which have therethrough openings or apertures 5, for the passage of U-shaped clips through the looped portions of which are passed wedges 6 to connect and draw the flanges together when adjacent plates are connected. Each of the side-plates l, have attached thereto bars 7 that are arranged in pairs, the bars being shaped and spaced to provide between the bars ways 8, such ways being iii line with the spaces Between the longitudinal Figs. and 15" side-plates. Figs. l and 5 are sectional viewr wall.

The plateties 10, have their horizontal.

necting thereto a- ,detachable frame that is used more particularly in building a wall by successively molding single blocks.

Both of the side-plates are identical in construction and size s'o that when'placed edge to edge the apertures will register and in position for forming a wall of the desired thickness, and after the cement has set the cross-bars are removed for reuse. The cross-bars 10 which do not form a permanent part of the wall have flanges 1-1 and slots or apertures 12 for the reception of wedges 13 which abut .or contact with the side-plates above and below their vertical flanges, as shown by Fig. 3, and the shoulders on the plate-ties or cross-bars 10 will bear against the inner faces of adjacent plates. Instead of forming the ends of the plate-ties as shown by Fig. 1, with horizontal flanges and a central web, the same may be made from a crossbar 10 see Fig. 7 and with such form of bar the slots 12 will be extended and a spacing wedge 13 with steps will be used, such construction or arrangement being used with outer wedges 13, which have one straight face and the other inclined, by the use of the step-wedges 13 and the long slots means are provided for varying the distance between the plates and the thickness of the flanges cut away to form recesses 141 to hold in place division plates 15, used in the construction of hollow walls. In constructing hollow walls it is desirable to use wall-ties and with the structure shown by Fig. 1 I use wall-tics as shown by Fig. 6,'such ties 16, being made of a flat strip of metal the ends being slitted and bent in opposite directions, and in practice these ends will be positioned so as to lie about midway between the sidesott the hollow wall. In using the ties 16, they may rest upon the plateties 10 and between the vertical plates 15.

In connection with the side plates 1, I use corner-sections 17 which are made up to carry or have attached thereto lever supports 17 which are cut away or shaped to receive the fulcrum of a lever 18, the short end of the lever being adapted to engage with a slotted piece 18 secured to one of the sidepieces 1, the slot havingenlarged ends to admit of a headed pin on the short arm of'the lever being passed through to ei'igage the narrower portion of the slot. The part- 18 maycxtend from one end flange of a plate to the other end, or it can be attached to one end flange and engage with the bars or braces 7.

The corner sections of the mold may be made so that the wall exteriorly will project,

. and in every instance there will be present of a tube 20, both ends of the tube pcing .shtted and bent to provide parts 21 the ends 21 of which are bent so that the opposite ends 21 will extend one toward the other, :r: shown, and other parts 22 are bent toward the center and are cut away to provide in ward projecting portions with whiclrthr tics 10, for the side-platcs may engage to center the ties thereon, or to receive the threaded ehds of; conical sockets 23, the larger ends of the sockets having an opening through which are passed headed slides 24 that are provided with slots for the passage therethrongh of wedges 13, that impinge against the plates 1. as shown in Fig. 3 of the drawings. The wall-tics 20. and ll) have tornicd therein recesses "26, for the reception of plates 15 that form the inner walls of the molds in making hollow walls.

A hollow *all or a section thereof may be molded by using two side plates and an end plate 27. which in use will be attached to an end of the side plates by U-shapcd clips and wedges, as shown by Fig. 14, and to provide means for connecting the sides 1, I provide a frame that comprises on each side bars 28 that may be seated. in and secured between the flanged bars 7 attached to the outer faces of the side-plates 1, the bars 28 extend above the side-plates '1 and are provided with bolt holes through the parts that extend upward and to the bars 28 there is secured a transverse bar 29 and arms or links 30 which are pivotally connected or bolted to the upper ends of the bars 28 and are in turn connected to crossed arms or links 31 which are pivoted to the upper ends of vertical bars 32 which are fastenedto the inner faces of the core plates 15, such bars 32 having form-ed thercthrough slots 33 for the reception of studs aim the lower ends of the links 31. The links at their point of intersection are connected pivotally to an internally thread-- ed nut 35 through which passes a screw 36 that has above its threaded portion a collar 37 which by engagement with flanges 33 on a plate 39 holds the screw against longitudinal movement and the screw is turnedby the handle 40 that is fast upon the upper end of the screw. The plate 39 which extends across the mold has its ends bent, one end being formed into a. hook 41 and the other end extends downwardto receive a screw or bolt 42 the end lying under the outward extending flange on llllQOlltQl side p1ate1.- \Vhcn the parts shown by Figs. 9 and 14 areposi- V indicated the inner mold plates i ll. hear in the recesses 26 tortured in the ie 20 and the upper edges will shut lugs 43, which depend from the he il outer plates and has set or harcross her or piece 39 is released so .3, have s slight upward movement CIQW is turned, suilicient to release from the recesses in the tie i 1 having the recess 26 and when the screw is turned t more the nut upwsrd which move to turningthe screw the holtlil is d the hoe-it detached to admit of ,oveinent of the outer plate nstances it is desired to rougher). inner face of the well end. to the or" face, the inner face being W replaster and the outer ,s other finish or shape, as imitation of one, to accomplish this end the ll llltll'. pl e may he overlaid by e grille or sceen attached to end strips l t, see Fig. n'l'iich will overlie the vertical flanges of the plate 1 and he attached thereto by clips ees. The outer plate is also proh a shaping plate to give the de finish to the outer face of the Wall and h shaping plates 1-5and.scoringtrainees 46 applicable to assembled side plates when in the construction of either solid or Walls.

curse it should be desired to use the no illustrated by Figs. 9 and M in Inoldlid wall for u foundation or footing my disconnect the links 31 from the links removing the crossed links 31 and the piece 39, and after the removal of these the outer ends of the links 30 are at- "inched to the cross-bar 29 serving when con to hold the sides 1 in parallel aliner use. When such parts are used, r plutcslli, bars 32 and cross piece not he used and the bars 30 are at to the ends of the bar 29the upper t mold plates will be held in pan f ineinent. 2 often desirable to form grooves or in the outer face of the wall to iiloclts-i of stone and to form such rcc: v use either strips 47 or 48 as shown by Fine. ll und l2, Whichare placed between the mold tes so that parts may extend in ward and indent the concrete or outer Wall opposite the ioints between the mold plates. The strip il-Ll has n flange with openings which ore spliced to register with the openthrough the flanges ot the nletes l, and

e that the mold may he raised, but

whcn secured in pl tween the plates. verticully and ho i'ontully, and, when used a scoring plate 442 1g. 19 will'he used h to n the joints of the ear plate in order that the connected plates on both sides may he of the same length. When a strip 47 is used the ends are notched and such reduced ends will he overlaid either by a ring 50 as shown in Fig". 5, which will abut against the flange of the plate tie 10 or as shown by Fig. 4 against the ends of the parts 23. When the strips it? are used to form recesses in the face of the outer wall scoring means it will he used on the inner laces oi the pistes 1 that term. the inner face of the mold.

The parts herein described. form a complete outfit for constructing either hollow or solid trolls (If the desired thickness, for tootings, foundations and partitions which may be solid while the external walls Will he hollow. and constructing building's no outside so aiding will he required which material reduces costs.

.-.i1e concrete may be poured or used in plastic condition to he tamped while being placed in the molds, and when the cement has set in thetrough-mold made up of a. series of connected plates, the lower plates are disconnected from those above by removing the clips and Wedges and levers 18 are caused to engage the fulcrum plates 17 and the slotted plates 18', the levers are moved simultaneously outward and carry the plates beyond the flanges and then by raising the levers the position of the plates may he cl enged to rest upon those above and after being clipped and wedged in place are ready to receive cement The bars or insane for holding the plates may he left in the wall until it is hardened and when in place carry a greater portion of the weight of the molds, a part also being; carried by the Wall ties 20. @itten it is desirable to-use a short or half plate in order that the joints on the dilierent rows may break joints as shown by 13, such a short section may he used and. is preferably constructed as shown by 9 of the drawings.

To close the openings between the ends of the plates 15, 15, ll use 'l-hars 51 which are of a length to engage with the undersideot' the tie-liars 10 or il the fiange'of the bars are passed through the spaces between the plates and then bars 52. which are elliptical in. cross section are passed through openings 53 through the flanged bars 51 and when turned will jam against the inner faces of the plates 15 to prevent the same buckling or bending. see Figs. 1, 15 and 15. As the openings extend through the center flanges and the bars 52 are about the same width as the circular openings such liars when turned fror'n a horizontal position will bear against the inner face of the plates 15 and the side of the opening farthest from the point of contact,

The bars may have an opening thereth'rough for the reception of a bar or rod for turning the same or a handle 5t may be attached to the har.

In a mold as shown by Figs. 1 and 9, the end plates 27 will have slots 27 for the passage of longitudinal tie bars 27.

The construction of the several parts may be modified or changed as it is desirable in the make up of both single molds that are used in building walls from rather stifl cement which is tamped or rammed, and in connected forms for building walls from cement of a consistency that it may be poured to use as .t'ar as possible stock material cut and shaped in proper "form.

The leading idea of my invention is to provide means for constructing 'alls by the use of one set of molds which can be used to make footings or foundations, hollow exterior walls and solid thin partition walls by merely varying the length of the moldtics or con ectingi bars between the vertical plates of the molds.

With the means illustrated it will be unnecessary to erect exterior scatlolding as the molds may be manipulated entirely from platforms sustained by the floor beams which are put'in place as the construction of the walls progress.
